Use Slack Channles
I found this idea in a tweet from Reilly Chase founder of successful SaaS products.
1. Join Slack communities where your potential customers hang out. If you are not sure where to find the right Slack Community you can use a website called Slofile.
2. Change display name to "Your Name (Your Company)".
3. Set up keyword notifications to jump into conversations where you can provide value.
4. Don't just promote your product! - Be helpful and provide value.
